74Ï€
radians
Â
To change from degrees to radians use the following formula:
Â
degreesâ‹…(Ï€
radians/180 degrees)
the (Ï€180)
means that for every π radians you go around the unit circle, you've gone 180
degrees.
Â
So, taking our 315
degrees and plugging into our equation we get:
Â
315
degreesâ‹…(Ï€ radians/180 degrees)
The "degrees" cancel out, then we are left with:
Â
315180â‹…Ï€
radians
Â
315
and 180 are both divisible by 45
, so
Â
315180=74
Â
So, then we just need to multiply by π
radians and we get:
Â
74â‹…Ï€
radians = 74Ï€ radians
